Tension between South and North Korea advanced now. Both claimed not open first strike that triggered war.
North Korea will launch additional attacks on South Korea if it continues "reckless military provocation," the North's state media said Thursday.
Pyongyang "will deal without hesitation the second and third strong physical retaliatory blow" if provoked, its KCNA news agency said.
As an example of provocation, it indirectly referred to a military drill that South Korea and the United States plan to hold in the Yellow Sea starting Sunday.
